MICRO-ALLOY STEEL COMPOSITION WITH IMPROVED MECHANICAL PROPERTIESThe invention particularly relates to a micro alloy steel composition comprising; carbon (C) in a ratio of 0.15 - 0.2 % by weight, nitrogen (N) in a ratio of 0.007 % maximum by weight, silicon (Si) in a ratio of 0.25 % ...
It is an important micro-alloying element and alloying element in the steel. The addition of vanadium into steel can enhance the strength, toughnes... Y Gan,H Dong 被引量: 4发表: 2010年 Study of the Effect of W and Mo Binary Alloying on Fe-Ni36 Invar Alloy Properties The element W,...
This paper introduces the importance of weldability and welding joints' properties during the development of new generation high strength low alloy steels( HSLA). Weld joint properties depend on the weld joint microstructure. Weld joint microstructure is generated in the welding solidification and the ...
As a general indication, low alloy steel can be regarded as alloy steels (by the ISO definition) containing between 1% and less than 5% of elements deliberately added for the purpose of modifying properties. Micro-Alloyed Steels A micro-alloyed steel can be defined as a carbon-manganese steel...
Micro-alloyed steels cost less than carbon steel and low alloy steel and have been materials of choice in auto mobile and oil and natural gas industries [4]. This excellent combination of properties can be attributed to the presence of fine grain structures achieved by the addition of small ...
An Al-5.8Mg-0.4Mn-0.35(Sc+Zr) (mass fraction,%) alloy sheet was prepared using water chilling copper mould ingot metallurgy processing which was protected by active flux. The influence of stabilizing annealing on mechanical properties and microstructure of the cold rolling sheet was studied. The...

A micro-nanostructured WC composite coating with agglomerate nanostructured WC particles and micron WC as the reinforcing phases was fabricated on Q235 steel by induction cladding with Ni60A, micron and nanostructured WC alloy powders as the raw materials. Microstructure of the coating was characterized ...
The invention relates to a microalloy non quenched and tempered steel for an automobile axle head, which is characterized by comprising the following chemical compositions in percentage by weight: 0.27-0.37 percent of C, 0.15-0.35 percent of Si, 0.80-1.40 percent of Mn, 0-0.030 percent of P...
